PANEL FOR USE IN THE CONSTRUCTION OF CARS, BOATS, 80c.

SPECIFICATION forming part of Letters Patent No. 311,022, dated January20, 1885.

Application filed June 21,1815-l. (No model.)

ing of the parts, is effectually prevented, while at the same time, whenclosed, the air may have free circulation around the same and throughthe stateroom and vision be completely cut off.

In order that the invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which-Figure I is a perspective view of one of the improved sliding panelsremoved. Fig. I[ is an elevation of the same in position in the frame.Fig. III is a horizontal section thereof.

The invention is specially adapted for use in the construction ofsleeping-carssuch as described in my contemporaneous application filedon the 25th of March, 1884, Serial N o. 125,45l-but is applicable to anystructures where found desirable.

I may represent the wall or partition which separates the state-roomfrom some other apartment of a structure, being provided with grooves orchannels 2, which confine the panels 3 and permit their free verticalmovement, as hereinafter explained. The panels 3 are constructedwith-tongues 4, which are short vertically, and project horizontallyfrom the upper and lower corners thereof, and enter the vertical grooves2 in the partition 1. By the use of these short tongues 4 the panels areeffectually confined, while being adapted to slide freely up and downwithout the dangcr of cramping, or binding, which is liable to occurfrom the warping ot' the parts, caused by changes of temperature, orfrom straining or unequal settling of the jamb when the edges of thepanels engage throughout their length in the guiding-grooves. The edgesof the panels between the tongues 4 are beveled, as shown at 5, thebeveled portions projecting within the guiding-grooves 2 withoutcontact, so as to completely exclude vision, while at the same timepermitting the free circulation of air around the same and precludingthe liability of the panel to stick or jam. These sliding panels may beprovided with lifts and locks of any suitable form on the inside,enabling the occupant of the room to move or tightly secure the panelsat pleasure.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

The sliding panels, substantially as hereinbefore described, constructedwith guidingtongues for a small portion of their length, and with a thinor beveled edge for the remainder thereof, in combination .with a frameor jamb having guiding-grooves, into which said tongues and edgesproject, as and for the purpose explained.
